1. why the hell does idate not recognize naruto or sasuke? sure its understandable that they not recognize him as hes is just your average ninja, but idate would know who both sasuke and naruto were. this is because sasuke is the last of his clan in the village and i imagine it would be pretty common knowledge that a slaughter took place and as the clan is so revered idate woudl recognize the symbol on his back. naruto woudl be known to almost all the villigers surley?
Oh give him a break do you know everyone in your town? Idate is 3yrs older then them so there is no reason why he should know about his under class, heck even Neji didn't know who Sasuke was and he is only a yr older.

2. why the hell did chidori (a thrusting assasination technique) fare better against that sword than rasengan (wich for all the ties weve seen it seems to be more of a physical push)??? and why the hell does the genius ninja sasuke use the same technique TWICE? and WHY THE HELL doesnt his sharingan allow him to predict that..........HES NOT GOING TO MOVE AT ALL he just runs right into it.
It's called Lightning Edge for a reason, like Gai said it cut through a lightning bolt so a sword made of lighting should have the same effect. Plus the sword isnt even that strong it'd melt butter before it cut it.

On to the ep, I actually liked it.
